To all whom it may concern: Be it known that I, GEORGE C. WALTER, a citizen of the United States, residing at Hastings, in the county of. Barry and State of Michigan, have invented a new and useful I Process of Treating Hides, of which the followingv is a specification.

, My invention relates to an improved process for treating hides which after treatment, are especially adapted for use as halters; and it has for its object to provide a process to be performedin' conjunction with certain ingre dients forming certain compounds that will hasten the completion of the-tanning of the hides after the-removal of the hair to save tnnch time and labor,-'also rendering the leather stronger. ndm'ore durable and impervious to wat The process'a-is as follows: After the removal 'Qf thG hai-rzfnom the hides by the ordinary means they hides are placed into a solution composed cftwenty-five ounces of oil of vitriolpthree' quarts-of salt, six pounds of alum, and twelve gallons of water, the proportions of which-may be variedfaccording to the numberof-hides to be treated. The hides are allowed to remain in the above solution forty-eight hours, are removed, and sleeked,

when the same will be ready to be placed in a mixture composed of fourqnarts of soap, one

quart of lard-oil, one quartcodbil, and twelve quarts of water, the proportions of,these ingredients composing this solution being also regulated by the number of'h'ides to be treated, the effect of this second compound being toovercome anysubsequent chemical Having described my invention, what I claim isw I The herein-described process of treating hides, consisting, first, in subjecting the hides from which the hair-has been removed to the action of a compound consisting of oil of vitriol; salt, alum, and waterffor about fortyeight hours,'then removing-them from this solution and sleeking, then placing them ,in

a mixture composed of soap, lard-oil, cod-oil, and water to overcome subsequent chemical.

efiectsfrom the first compound and also to impregnate the pores of the hides and render 7 ,them impervious to'water, then removing them from this second solution and-drying them by exposure, to hot or cold'air, and finally breaking and sleeking them as before, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aifixed my signature in presence of two witnesses.
